No.
Any coding LLM could probably help you piece together the kernel configs, makefiles and so on but you can’t just tell it “build me a linux distro called Mannah Hontana”.

Edit: not to mention that distro is more then just the kernel, there is also the choice of init system (what will start and manage “background” services), package manger (so also the package format), desktop environment (kde, gnome, …none) and so on

I am currently in the market for a new mobile phone. The current’s one battery is basically dead and because of security patches now being about 2 years old I have to replace it whole instead of just getting the battery replaced again.

Pixel with GrapheneOS has been my number one choice for some time but…

1. there is no (privacy friendly & legal) replacement for Google Play Protect. My banking app won’t work without it as well as one other app I kind of need too.
2. I am also just too used to having a phone in the 250-300 EUR range in the sense that I don’t have to care about it that much.
   It’s a “consumable” product for me. Loosing/drowning it is not a big deal, where drowning 800 euros is just hard to justify no matter how much money I make.

I will probably just get the OnePlus Nord 4 instead because of their pledge to do 6 years of updates.
